About Blue Water Facts
Blue Water Facts is a generated reference site about ocean container shipping.
So we built the reference we wished existed. In July 2026 an internal audit found that our per-carrier ISO 6346 owner-prefix registry could not be reliably verified against the Bureau International des Containers for most long-tail carriers, so we removed that feature (see /accuracy/ for the full findings).
Blue Water Facts is reader-supported. We accept advertising in the form of contextual display units (clearly labelled as Sponsored) and we partner with a small number of editorial sponsors whose links appear in the sidebar and footer. We do not accept payment for inclusion in our directory and we do not write paid carrier reviews. If you find an error in our data, please write to editor@bluewaterfacts.com with a public source and we will correct it within 48 hours.
On 2026-09-16 the carrier profile prose (founding years, fleet sizes, headquarters, operating models, alliance status, trade lanes and contact details) and all 35 trade-lane pages were removed: those figures had been generated from a template, not recorded from any source, and at least 21 profiles contradicted themselves. What remains is the prefix-registry accuracy report, the how-to-track guidance, the ISO container format reference and the alliance member lists.
You can begin exploring the reference from any of the three main hubs:
- Carriers — the carrier directory.
- Alliances — Gemini, Premier, Ocean Alliance and historical partnerships.
- Container formats — every ISO container type with full dimensions.
